&#60;Shift-Click&#62; toggles the grid visibility

This is an implementation of a meshwarping algorithm, using polygon scan conversion with texture
mapping to produce the warped image. On release of the mouse button after modifying the position of a vertex, the four affected polygons incident on the modified vertex are rendered with a relatively standard Bresenham incremental scanline conversion [...]]]></description>

This is an implementation of a peculiar triangular morphing algorithm. Starting with a source image, a destination image, and three control points for each image, I basically divide each image into a mesh of triangles, using the four corners and three control points as vertices. These triangles are then split into what I call simple [...]]]></description>
